Not necessarily because the relative speeds will be very slow. Not so in low lunar orbit, where an orbiting spacecraft will slam into the ejecta curtain at x km/s.

The paper estimates that if there's LLO debris, it'll be starting out with about 1.6km/s of surface-relative velocity. Not something you want to get even a small percentage of on your landing gear.

My first time encountering this acronym. I can't wait until it's in common use and we have cities and communication satellites in and around the moon.

I guess you really like 1950s sci-fi.

Oh, that's a good point.
